Which is stronger H or I-beam?

Could you please clarify for me which structural beam is stronger, the H-beam or the I-beam? I've heard conflicting opinions on this matter and am trying to understand the relative strengths of these two beam types. In terms of structural integrity, which one is generally more durable and capable of supporting heavier loads? Additionally, could you explain the factors that contribute to their respective strengths, such as material composition, cross-sectional design, or any other relevant characteristics? Your insights would be greatly appreciated as I'm seeking to make an informed decision for a construction project. Thank you for your time and assistance.
